That is the most ridiculous thing I have ever read. The results are biased. The Festool Domino is the strongest joint on the planet. I read it on the internet. It is 5 billion times stronger than a biscuit. And we are off.
Edit to add:
Isn't a 10mm domino a 3/8" floating tenon?

Put a couple dowels in there and you have an even stronger joint.?
I had to look that up- never heard of the domino.

I'll have to dig out the results if I still have them (computer hard drive took a dump and it was not backed up) but I put a similar size M&T against a Domino at an Instron at work and they were dead even. In cherry the two joints were right around the 1050 pounds mark to get the joint to fail.
Edit to add: both joints failed the same way with the tenon(domino) splitting and pulling out of the cross grain piece.

Are you living under a rock?

I used a half lapped domino as a tenon and the wood turned to steel instantly.

My Domino beat up my doweling jig.

Is it just me or does anyone else think the second setting on the domino is way too wide?! That is the main thing i HATE about the domino.

For the smaller model it is (at least for me). That's why they changed variance on the larger XL model. I've never even used the 3 setting on the smaller model.

I don't know. Maybe it's not the size that matters but how you use it.
